Theory of strong down-conversion in multi-mode cavity and circuit QED
Nitish Mehta, Cristiano Ciuti, Roman Kuzmin +1
We revisit the superstrong coupling regime of multi-mode cavity quantum electrodynamics (QED), defined to occur when the frequency of vacuum Rabi oscillations between the qubit and…
Tuning the inductance of Josephson junction arrays without SQUIDs
Roman Kuzmin, Nitish Mehta, Nicholas Grabon +1
It is customary to use arrays of superconducting quantum interference devices (SQUIDs) for implementing magnetic field-tunable inductors. Here, we demonstrate an equivalent tunabil…
Superconducting resonators with voltage-controlled frequency and nonlinearity
William M. Strickland, Bassel Heiba Elfeky, Joseph O'Connell Yuan +6
Voltage-tunable superconductor-semiconductor devices offer a unique platform to realize dynamic tunability in superconducting quantum circuits. By galvanically connecting a gated I…
Microwave cavity-free hole burning spectroscopy of Er:YSiO at millikelvin temperatures
Anton Mladenov, Natalia Pankratova, Dmitriy Sholokhov +3
Efficient quantum memory is of paramount importance for long-distance quantum communications, as well as for complex large-scale computing architectures. We investigate the capabil…
Demonstration of the Two-Fluxonium Cross-Resonance Gate
Ebru Dogan, Dario Rosenstock, Loïck Le Guevel +7
The superconducting fluxonium qubit has a great potential for high-fidelity quantum gates with its long coherence times and strong anharmonicity at the half flux quantum sweet spot…
Down-conversion of a single photon as a probe of many-body localization
Nitish Mehta, Roman Kuzmin, Cristiano Ciuti +1
Decay of a particle into more particles is a ubiquitous phenomenon to interacting quantum systems, taking place in colliders, nuclear reactors, or solids. In a non-linear medium, e…
